The Formation of Carbide-Free Bainite in High-Carbon High-Silicon Steel under Isothermal Conditions

摘要

It is shown that a carbide-free bainite structure can be formed in high-carbon steel of the Fe-Si-Mn-Cr-V system using a traditional furnace facility. The structural aspects of bainitic transformation developing under isothermal conditions at 300A degrees C have been studied by the methods of X-ray diffraction and transmission electron microscopy. Orientation relationships between crystalline lattices of gamma and alpha phases have been established. A superequilibrium carbon concentration in the bainite alpha phase has been determined.
